What is y=4/5x+2 written in standard form
shepuryov [24]

Answer:

4x-5y=-10

Step-by-step explanation:

we know that

The equation of the line in standard form is in the form

Ax + By = C

where

A is a positive integer, and B, and C are integers

In this problem we have

y=\frac{4}{5}x+2 ----> equation of the line in slope intercept form

Convert to standard form

Multiply by 5 both sides

5y=4x+10

4x-5y=-10

Given the function f(x) = 4(x + 3) -5, solve for the inverse function when x=3
daser333 [38]

Answer: Your answer would be -120

Step-by-step explanation: Remove Parentheses (3 + 3) add them together and make it 6 and plug in the 6 into the equation. -4 x 6 x 5. Then, you multiply the numbers together and get -120. There is no inverse for -120 since both sides aren't equal.

I hope this helps you!!
